what does Matlab provide wrt this? Does its editor have refactoring assistance now?

do you mean package creation?

what kind of collisions do you mean?

what would your ideal tool for this look like? you select parts of your REPL history, ask for some name changes in it, give it a package name, and have it generate a package? any other features or steps that come to mind as potentially helpful?

Matlab has some simple refactoring for names changes. Change a name and press shift+enter to change all other occurrences in the file.

Yes, package creation. The "right way" use create package.jl or whatever feels like a speedbump and requires setup.

When I import the newly created model, I have gotten name collisions with the playground remnants which you can't fully clear without restarting the repl.

That sounds like something I'd use, yeah. If you wanted to be fancy, you could make a function, putting uninitialized values into the argument list.
